Handling Multiple Github Accounts on MacOS

The only way I've succeeded so far is to employ SSH.

Assuming you are new to this like me, first I'd like to share with you that your Mac has a SSH config file in a .ssh directory. The config file is where you draw relations of your SSH keys to each GitHub (or Bitbucket) account, and all your SSH keys generated are saved into .ssh directory by default. You can navigate to it by running cd ~/.ssh within your terminal, open the config file with any editor, and it should look something like this:

Host *
 AddKeysToAgent yes

> UseKeyChain yes

#   IP returned by above commmand is VIP of cluster api servers.

ssh root@<supervisor-node-ip>

NOTE: don't use this method if you have alternate way to fix it by using any other user with clients.write scope

If you have removed uaa.admin scope from TKGi 'admin' user, here are the steps to fix it by db method

• bosh -d <pks...> ssh pks-db/0
• sudo su -
• mysql --socket=/var/vcap/sys/run/pxc-mysql/mysqld.sock -u uaa -p
• <password should be from TKGi tile 'Cf Mysql Uaa Db Password'>
• use uaa;
